The intended audience of my efforts is "Matlab crowd" who are
accustomed to a concept of free lunch. Of course, a "real programmer"
will allocate all the memory manually:-) Seriously, though, I do agree
with you. It is for a good reason that time honored high performance
libraries such as BLAS or LAPACK let users manually handle the
resources. It gives them full control and after some practice is not
that hard. But in today's world of shortcuts and instant gratification
it is expected that the "platform" is smart enough to do all sort of
boiler-plate stuff.

Give me "do_what_I_mean()" function call, pleease!:-)
